In 2012, a GHG research network referred to as MAGGnet (Managing Agricultural Greenhouse Gases Network) was established within the Croplands Research Group of the Global Research Alliance on Agricultural Greenhouse Gases (GRA). With involvement from 46 alliance member countries, MAGGnet seeks to provide a platform for the inventory and analysis of agricultural GHG mitigation research throughout the world. To date, metadata from 315 experimental studies in 20 countries have been compiled using a standardized spreadsheet.

were completed (74%) and conducted within a 13-year duration (68%). Soil carbon and nitrous oxide emissions were measured in over 80% of the studies. Among plant variables, grain yield was assessed across studies most frequently (56%), followed by stover (35%) and root (9%) biomass. MAGGnet has contributed to modeling efforts and has spurred other research groups in the GRA to collect experimental site metadata using an adapted spreadsheet. With continued growth and investment, MAGGnet will leverage limited-resource investments by any one country to produce an inclusive, globally shared meta-database focused on the science of GHG mitigation. GRA Global Research Alliance GRACEnet Greenhouse Gas Reduction through Agricultural Carbon Enhancement Network MAGGnet Managing Agricultural Greenhouse Gases Network Introduction Concurrent efforts to mitigate agricultural greenhouse gases (GHGs) while adapting production practices to projected hardships of climate change will be essential to ensure long-term sustainability and food security [1,2]. Mitigation research in agriculture should provide a mechanistic understanding of the underlying processes affecting natural resources, be scalable to provide useful predictions, and be translated in such a way that it effectively supports both adoption of best practices/systems and informed decision making for policies [3]. Although a significant number of research projects have been completed or are underway to understand how agriculture can mitigate GHG emissions, a coordinated effort is lacking to catalogue and synthesize disparate research efforts around the world. In response to these challenges, the Global Research Alliance on Agricultural Greenhouse Gases (GRA) was formed in 2009 to develop trans-national strategies for reducing GHG intensity of agricultural production [4]. To facilitate focused efforts, the GRA established three research groups (Cropland, Livestock, Paddy Rice) and two cross-cutting teams (Soil CarbonNitrogen Modeling, Inventories-Monitoring). Each group and team developed work plans to enable successful collaborations, as well as to share knowledge and best practices, build capacity and capability among participants, and move towards transformative solutions to reduce agricultural GHG emissions ([5] GRA, 2016). Membership in the GRA is voluntary, and 46 countries have already become members of one or more GRA research groups and/or cross-cutting teams (verified May 10, 2016). The organizational platform of the GRA facilitates the development of research networks. As reviewed by Baldocchi et al. [6], networks occupy a central role in GHG research. Broadly, GHG networks provide a forum for generating creative solutions to critical mitigation challenges using diverse perspectives. More specifically, data archives and management activities often serve as a key focus for GHG networks, given the complexity of the subject and the need to provide data for the development and testing of models. Modeling efforts and meta-analyses that use high-quality data archives from GHG networks provide critical information to predict GHG emissions from agricultural activities and inform policy decisions focused on mitigating emissions [7]. Here, a GHG research network formed under the auspices of the GRA Croplands Research Group is introduced. Referred to as the Managing Agricultural Greenhouse Gases Network (MAGGnet), the network represents a coordinated, multi-national effort that serves as a foundation for inventory and analysis of GHG mitigation research. Through this brief report, MAGGnet’s development, metadata collection method, current status and recent applications are described. Development and description MAGGnet arose from member discussions during the GRA Croplands Research Group annual meeting in San Antonio, Texas, USA, October 20, 2011. A key action item identified during the meeting was the “development of an inventory database on long-term measurement experiments,”which was distilled from a broader goal to create a global network of reputable GHG emission and soil C sequestration data from specific management practices for synthesis evaluations and model testing/validation across a diversity of environments [4]. Following discussions with Croplands Research Group co-chairs in late 2011, the action item was focused to compile key metadata from cropland experimental sites throughout the world where biomass yields, GHG flux and soil C dynamics were monitored. Experimental sites with a record of documented outcomes in peer-reviewed publications were targeted, a limitation intentionally imposed to increase the likelihood of compiling high-quality metadata. Metadata from experimental sites were compiled using a Microsoft Excel spreadsheet (Microsoft Corp., Redmond, Washington, USA). Loosely patterned after a data entry template used by the Greenhouse Gas Reduction through Agricultural Carbon Enhancement Network (GRACEnet) [8], 11 worksheet tabs were established to collect background information and experiment metadata. Within the spreadsheet, a 244 M.A. LIEBIG ET AL.
User Guide/Directions worksheet served as the leftmost tab, and was followed by Experiment Description, Experiment Location, Experiment Duration, Climate Attributes, Soil and Drainage Attributes, Data Type, Treatments, Key Findings, Journal Citations and Primary Contact worksheet tabs (Table 1). To facilitate efficient metadata entry, general instructions provided within the User Guide/Directions worksheet tab were supplemented by strategically placed comment boxes throughout the spreadsheet for additional guidance. Input variables requiring Yes/No responses used drop-down menus, as did numerous variables within the Soil and Drainage Attributes and Treatments worksheet tabs. A beta version of the MAGGnet spreadsheet was developed, pre-tested and revised in February 2012. Version 1.1 of the MAGGnet spreadsheet was released to GRA Croplands Research Group members in March 2012. Following the first round of metadata collection and comments from GRA members throughout 2012, version 1.2 of the MAGGnet spreadsheet was released in December 2012. Version 1.2 incorporated additional response categories and improved directions/guidance within most worksheet tabs. To address potential concerns dealing with intellectual property rights associated with sharing and using metadata from multiple countries, a metadata sharing agreement was developed in 2014 and posted on the GRA website (see Supplementary material). Metadata synopsis As of August 2015, there were 315 experimental studies included in MAGGnet (Table 2). Studies were distributed across 20 countries, with over 50% located in France, the United Kingdom and the United States (Figure 1). Studies were spread across 14 K€ oppen-Geiger climate subdivisions [9] on 11 surface soil textures (data not shown). Seventy-four percent of the studies were completed, with the balance ongoing. Most studies were 13 yr in duration (68%), while 17 and 15% of the studies were conducted over 310 yr and >10 yr, respectively (Table 2). Over 55% of the ongoing longterm studies were located in Italy, Switzerland and the United States. Table 1.

Soil carbon, an important metric for quantifying cropland GHG mitigation potential [1], was monitored in 83% of studies included in MAGGnet (Table 3). Among GHG flux measurements, nitrous oxide (N 2 O) was measured most frequently across studies (82%), followed by carbon dioxide (CO 2 ; 45%) and methane (CH 4 ; 29%). Grain, stover and roots were assessed in 56, 35 and 9% of the studies. Treatments most commonly measured in MAGGnet included fertilizer rate, manure/ soil amendment and tillage type, included in 68, 52 and 43 studies, respectively (Table 4). Emphasis on such management practices was unsurprising, as they corresponded to an overarching goal of generating recommendations to mitigate agricultural GHG emissions. Despite the explicit cropland focus within MAGGnet, 29 sites included a pasture/grazing system (Table 4). Data submissions from this land use were encouraged given the clear engagement by researchers focused on grazed systems and the strong linkages between grazed lands and imported feed from cropland. Insights that emerge from concurrent analysis of cropland and grazing land management are likely to contribute to new integrated approaches for increased food production with lowered environmental impact [10]. Recent applications Despite its recent emergence as a GHG network, MAGGnet has served to leverage limited resource investments within individual countries to produce an inclusive, shared meta-database for use by all GRAmember countries. While its potential as a functioning network has yet to be fully realized, MAGGnet occupies a unique niche among GHG networks given its geographical domain (global) and intended focus (cropland) [7]. With time and continued effort, MAGGnet can serve to further GHG mitigation science through new collaborations among contributing members. Figure 1.

MAGGnet has contributed to modeling efforts since its inception, and has spurred other research groups in the GRA to collect experimental site metadata. MAGGnet was used in January 2014 to help identify experimental sites for potential inclusion in an international model intercomparison exercise coordinated by the GRA Soil CarbonNitrogen Modeling cross-cutting team [11]. This ambitious exercise, involving 28 models used in 11 countries, seeks to quantify prediction accuracy among models for estimates of crop yield, grassland dry-matter production, N 2 O emission, net CO 2 exchange and soil C stocks. In other work, the Global Research Alliance Modeling Platform (GRAMP) was created to facilitate development, evaluation and adaptation of ecosystem models for estimating GHG emissions from agroecosystems [12]. GRAMP currently includes selected metadata derived from MAGGnet through an interactive map ([13] GRAMP, 2016). Finally, the MAGGnet spreadsheet was adapted by members of the GRA Paddy Rice Research Group in August 2014 to gather metadata from experiments focused on rice production. As of August 2015, metadata from 13 sites across five countries were included in the adapted spreadsheet, which included additional input metadata related to weather variables, field type, and water and rice management. Open invitation MAGGnet was initiated in the spirit of advancing GHG mitigation science through a multi-national research effort facilitated by the GRA. The value of MAGGnet to the scientific community will be directly proportional to its capacity to provide useful information for the analysis of GHG mitigation data. As currently organized, MAGGnet serves as a conduit for that purpose, with an explicit focus on metadata. We believe the focus on metadata was an appropriate “first step”to illustrate potential value. We envision the voluntary addition of key response data will provide even greater value to the scientific community as the “next step.” Information from additional studies continues to be entered into MAGGnet. Researchers interested in contributing or accessing metadata from experimental sites with published outcomes are encouraged to contact the corresponding author for the most recent versions of the MAGGnet spreadsheet and metadata sharing agreement. Alternatively, the spreadsheet and sharing agreement may be obtained through the GRA Croplands Research Group website (http://globalre searchalliance.org/maggnet).
